 of bark, weeds, and caterpillars' or spiders' web, with the lining

 times lacking. Length 4.75.

The nest is composed of fine grass, plant fibre, and down, 

 and lined with fine roots and hair, resembling to some extent the 

 nest of the yellow warbler. It is placed near the ground, in 

 scrubby bushes or saplings, often in young cedars. 3 to 5 eggs 

 are laid ; they are white, with a few brown or purplish brown 

 and faint lilac spots wreathed round the larger end. Size
